It’s a rising problem...something that’s happening more and more often. The simple answer is the fact that young kids nowadays simply play more baseball. 30 years ago, my teams were playing 15-20 games per year, with twice per week practice. Now some kids are playing 4 or 5 times that amount 9 months out of the year. In addition to kids playing more, injury diagnosis is much improved, and more doctors are able to do the surgery. Remember, this surgery has only been around 45 years, and for much of that time was viewed as a last resort. Now with 80+% success rates, and more doctors not only able, but willing to do the surgery, it’s not a surprise that it’s done more often.
